P2263 - Stuck turbo, MAP sensor, MAP hose plugged or leaking, CAC hose diconnected or leaking, intake leaks, exhaust restriction, exhaust leaks, EBP sensor or EBP tube plugged. This code is set when MGP does not go over 15kPa or 2.2 psi when the following conditions are met: rpm must be over 2800; VFDES above 35; and EGRVP above 0.10. All of these conditions must be met for 5 seconds for the code to be set. This code can also be set if there is ANY condition that would produce low power. For 2003 MY's, this code could also be set if the difference between EP_G and EP_DES is more than 14 kPa or 2 psi for greater than 15 seconds at idle or 60 kPa or 8.7 psi for 60 seconds above 800 rpm.
It is possible that the MAF is the original problem, but it could be a leak also ........

Funny enough, I just had a 2003 truck in with P2263 that was building almost no boost. It turned out to be a bad VGT solenoid. It was also the very first one I have ever had to replace out of the thousands of 6.0s I have wrenched on. But the checks that Mark described should be the first step.

How about check for intake leaks and exhaust leaks?
BTW, an EBP serves no useful purpose on a 2003 if your truck has had the Ford mandated 06E17 reflash that takes EBP input out of the PCM's strategy for determining the appropriate boost.
Verifying all the MAF sensor circuits between the PCM and sensor wouldn't hurt either. At least that'll be cheaper than the MAF sensor you'll buy that doesn't fix the problem, if doesn't turn out to be a bad sensor.
P2263 tells me your truck is not boosting, which can be caused by a sticky VGT or even a bad VGT solenoid. "Borrowing" a known good VGT solenoid to try on your truck would be something quick and simple to try too.

Okay, borrowing a MAF from another truck to swap in would also be another very quick test you can do.

Could be the case. But that doesn't explain the MAF code.
Best thing is to get something to read data with, see if the MAF reading is off. Then look and see if the VGT is moving as commanded. Then you will have a better idea. Otherwise you throwing good parts and the wrong problem, and these aren't cheap parts.
